ELECTRICAL CIRCULAR DUCT HEATERS
IMPORTANT:
If failure appears, power supply must be switched off and only then performed
fault elimination works.

Description of operating EKA NIS ...

Electrical duct heaters EKA NIS ... are designed for the heaters power (0...100) % control by
2
analog signal input (0...10) VDC.
When the heater power supply is switched on, LED 6 on the controller (EKR-KN...) PCB (see Fig.
11) flashes every second. If controller turns on the heating depending on analog signal, LED 5 lights
(see Fig. 11).
Description of operating EKA NV ... PTC ... (PH)
Electrical duct heaters EKA NV ... PTC ... are designed with integrated temperature control, PTC
2
(air velocity) and temperature sensors, potentiometer on the top of the heater casing for
temperature setpoint.
When the heater power supply is switched on, controller (EKR-KN...) is in preparing mode for 30
seconds, LED 1 flashes once every 5 seconds. If there is air velocity (Min. 1,5 m/s) in the duct heater
after preparing mode, LED 1 flashes once per second and controller turns on the heating depending
on the demand, LED 2 lights. If there is no air velocity, controller don't turns on the heating till air
velocity appears.
Heaters EKA NV ... PTC ... (PH) operates by the supply (TJ-K10K) air temperature sensor. Setpoint
temperature (0...30) °C.
There can be set the different desired (setpoint) air temperature by potentiometer on the top
of the heater casing.
If LED 1 lights continuously it means that there is a failure of: PTC (air velocity) sensor, supply
(TJ-K10K) air temperature sensor, potentiometer on the top of the heater casing.
When the heater power supply is switched on, after power supply interruption or after any
failure, controller is in preparing mode for 30 seconds.
IMPORTANT:
If failure appears, power supply must be switched off and only then performed
fault elimination works.
Description of operating EKA NI ... PTC ... (PH)
Electrical duct heaters EKA NI ... PTC ... (PH) are designed with integrated temperature control,
2
PTC (air velocity) and temperature sensors, wired remote control panel (TR5K) for temperature
setpoint.
When the heater power supply is switched on, controller (EKR-KN...) is in preparing mode for 30
seconds, LED 1 flashes once every 5 seconds. If there is air velocity (Min. 1,5 m/s) in the duct heater
after preparing mode, LED 1 flashes once per second and controller turns on the heating depending
on the demand, LED 2 lights. If there is no air velocity, controller don't turns on the heating till air
velocity appears.
